ResetSys
Purpose
Reset and initialize IEEE 488.2-compliant devices.
Format
C
void ResetSys (int boardID, const Addr4882_t *addrlist)
Visual Basic
CALL ResetSys (boardID%, addrlist%())
Interactive Control (Usage Notes)
ResetSys addrlist
Input
| boardID | The interface number |
| addrlist | A list of device addresses that is terminated by NOADDR |
Description
The reset and initialization take place in three steps. The first step resets the GPIB by asserting the Remote Enable (REN) line and then the Interface Clear (IFC) line. The second step clears all of the devices by sending the Universal Device Clear (DCL) GPIB message. The final step causes IEEE 488.2-compliant devices to perform device-specific reset and initialization. This step is accomplished by sending the message "*RST\n" to the devices described by addrlist.
Possible Errors
| EABO | I/O operation is aborted |
| EARG | Either an invalid address appears in addrlist or addrlist is empty; Ibcnt is the index of the first invalid address in the addrlist array. |
| EBUS | No devices are connected to the GPIB. |
| ECIC | The interface is not the Controller-In-Charge; see SendIFC |
| EDVR | The NI-488.2 driver is either configured incorrectly or is not properly installed. |
| EHDL | boardID is out of range. |
| ELCK | The requested operation could not be performed because of an existing lock by another process. |
| ENEB | The interface is not installed or is not properly configured. |
| ENOL | No Listeners are on the GPIB. |
| EOIP | Asynchronous I/O is in progress. |
| ESAC | The board is not System Controller. |
